简介
Modeling flood inundation in an urban setting is increasingly relevant given the magnitude of potential loss and disruption associated with non-riverine, urban flooding. Both complexities in the urban environment and lack of high-resolution topographic and hydrologic data compromise the development and implementation of models of non-riverine flooding in urban areas. This paper describes a case study analysis of an urban university campus to develop and test a GIS-based urban flood inundation model (GUFIM). The model consists of two components: a storm–runoff model and an inundation model. Cumulative surface runoff, output of the storm–runoff model, serves as input to the inundation model. The storm–runoff model adapts the Green–Ampt model to compute infiltration based on rainfall characteristics, soil properties, and drainage infrastructure conveyance. The basis of the inundation model is a flat …
